- Also known as: EUVD-2026-111597, GHSA-V79R-G77X-46WF
- Severity: CVSS 4.3 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial

## Affected

- hornero Clean Login: through 1.20.1

## Description

The Clean Login plugin for WordPress is vulnerable to Missing Authorization in versions up to, and including, 1.20.1 due to a missing capability check on the CleanLogin_Shortcode::get_pages_with_shortcodes() function hooked to the save_post action. This makes it possible for authenticated attackers, with Contributor-level access and above, to overwrite the plugin's cl_login_url/cl_login_id/cl_register_url/cl_register_id/cl_restore_url/cl_restore_id/cl_edit_url/cl_edit_id/cl_change_password_url/cl_change_password_id options with the ID and permalink of a post they themselves authored — simply by embedding the plugin's shortcodes in their own post content.
